Adding explicit externs to .c files is not wise as they may
conflict with those contained in system headers.

Does <netdb.h> or other header provide an extern for h_errno?
If not, we'll have to write a macro to detect the lack of an
h_errno extern, define a macro and conditionally provide an
extern (in include/ac/socket.h).
